INT 10 - Chips & Technologies Extended BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware.  The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. - GET SUPERVGA STATE BUFFER SIZE
	AX = 5F90h
	CX = state mask (see #00185)
Return: AL = 5Fh if function supported
	    BX = number of 64-byte blocks required
SeeAlso: AH=1Ch,AX=5F03h,AX=5F91h,AX=5F92h,AX=5FA0h

 2	DAC(Digital-to-Analog Converter) A hardware device (in its simplest form, nothing more than a set of interconnected resistors) which converts a digital number into an analog signal whose voltage is proportional to the value of the digital number.  VGAVideo Graphics Array and later color video boards use DACs to convert color values into the analog signals sent to the display; sound boards normally use DACs as well. state
